From Unofficial Ansalon Wiki

Ansalon is a Dragonlance MUD (Multi User Dungeon, Text Based Game) where a player can become an imaginary character in the DragonLance world, and interact with other players who are also playing at the same time. Your character can be a Silvanesti Elf, a Neidar Dwarf, a Human, a Minotaur, a fun-loving Kender, or any of a multitude of races.

Ansalon has been up and running since 1996. It is a stable, well-developed world, with custom code and custom areas to explore. Even over a decade later, we're making upgrades and changes on a weekly basis!
